bool update_padding_for_cl_image(arm_compute::ITensorInfo *tensor)
Container for 2D border size.
Definition: Types.h:273
static CLKernelLibrary & get()
Access the KernelLibrary singleton.
Store the tensor's metadata.
Definition: ITensorInfo.h:40
virtual size_t element_size() const =0
Element size in bytes calculated as data_size() * num_channels()
size_t get_cl_image_pitch_alignment(const cl::Device &device)
Helper function to get the cl_image pitch alignment in pixels.
Definition: CLHelpers.cpp:373
Manages all the OpenCL kernels compilation and caching, provides accessors for the OpenCL Context...
virtual const Strides & strides_in_bytes() const =0
The strides in bytes for accessing each dimension of the tensor.
virtual bool extend_padding(const PaddingSize &padding)=0
Update the offset to the first element, the strides and the total size.
